Anthropic merges Claude Cowork into the main Claude app and adds Docs and Slides

Sources: primary, discussion
Summary: Anthropic states that Claude Cowork is now part of the main Claude app rather than a separate product, and that the app gains Docs and Slides. The post is written in product terms and states nothing about sandboxing or about where the work now executes.
Why it matters: Cowork stops being a separate product with its own execution environment, which is the surface a published sandbox escape targeted in July, though this post makes no claim about that.
Follow-up: Track whether Anthropic states where merged Cowork work executes and how it is isolated.
